Most would think the watchtower is great for using a Bow, but since it's in the middle of the map and open to all sides, you'd be in more danger than anything. You'd also have to use the Kunai Climb skill to reach the top. You can, however, use the smaller side buildings for high ground. Your back will most likely be covered by your spawn area.

This is probably the most open stage out of the three. Running, hacking, and slashing can be found all over. You can try to hide near the cargo trucks for Ghost Kills, but most of the action will probably be around the watchtower.

Since this area is so open, you can use your Bow at just about any area.
